customer complains that paper jams right after fuser unit on 1st copy of the day or if it has sat for awhile. it didn't jam on me while i was out there. i cleaned all the paper guides before and after fuser unit and the side door (it was pretty dirty). cleaned all the paper feed rollers. removed and checked the fuser. i noticed the cleaning roller was caked with toner, would this cause the paper jam? they're just pain in the neck to clean, should i just replace it instead? fuser rollers (or film) looked fair. they bought this machine used so i don't know when it was serviced last. has about 200k i think. i noticed fuser units are very expensive.
any help would be greatly appreciated
thanks
